This is the most dangerous time for our planet – Stephen Hawking

“As a theoretical physicist based in Cambridge, I have lived my life in an extraordinarily privileged bubble. Cambridge is an unusual town, centred around one of the world’s great universities. Within that town, the scientific community that I became part of in my 20s is even more rarefied.

And within that scientific community, the small group of international theoretical physicists with whom I have spent my working life might sometimes be tempted to regard themselves as the pinnacle. In addition to this, with the celebrity that has come with my books, and the isolation imposed by my illness, I feel as though my ivory tower is getting taller.
